Top  Previous  Next

Any of the functions available in Geometry Expressions can be piecewise, including parametric functions.  Take this square for example.

1. Click the Draw / Function tool icon_function 

 

2. Select Parametric from the drop down Type window.

function parametric 

3. Enter the first value (side) for the square and the range for the parameter values -

Hit enter.  Don't worry about the shape of the function, it's not defined yet.

7. Now do the same for the y value, select the T parameter and click the Piecewise icon 3 times -

Use the arrow keys on your keyboard or your mouse to move to the next gray box.
